    Not possible to change the MAC Address of a network device to my knowledge.
    They are coded into the firmware of the device itself and assigned by the
    manufacturer. You can always put a second NIC in the machine and Nat thru
    it so it appears to come from a different NIC because in fact it would be.
    Does this help?

    Hi all,

    Is there any way to change the mac address of a LAN card in Windows
    2000 and Windows XP?

    As a corollary to the question, how would one detect if a computer
    was changing its mac address? This is assuming that the network on
    which this machine is connected has DHCP enabled.
